Ⅰ 求C语言高手,实现一个简单的TCPIP程序以实现两台计算机之间的聊天通信,
你上面给出的代码其实就是MSDN里面的演示代码,不过不完整,只演示了两个函数的使用,我给你看看我写的TCP通讯程序,可以在同一个局域网内的两台不同计算机之间聊天:
这其实就是某本将网络通讯的教程里面的例子,不过是我自己重写了一遍,下面给你代码:
========================
下面是公共代码:
========================
#ifndef__CINITSOCK__H__
#define__CINITSOCK__H__
#include<winsock2.h>
#include<iphlpapi.h>
#pragmacomment(lib,"ws2_32.lib")
#pragmacomment(lib,"iphlpapi.lib")
classCInitSock
{
public:
CInitSock(intnMinorVer=2,intnMajorVer=2)
{
WSADATAwsData;
WORDwVer=MAKEWORD(nMinorVer,nMajorVer);
if(0!=WSAStartup(wVer,&wsData))exit(0);
}
~CInitSock()
{
WSACleanup();
}
};
#endif
========================
下面是客户端的代码:
=======================
#include"CInitSock.h"
#include<iostream>
usingnamespacestd;
CInitSockg_Sock;
voidmain()
{
SOCKETsockClient=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
if(INVALID_SOCKET==sockClient)
return;
sockaddr_insockAddr;
sockAddr.sin_family=AF_INET;
sockAddr.sin_port=htons(4567);
sockAddr.sin_addr.S_un.S_addr=inet_addr("127.0.0.1");
if(-1==connect(sockClient,(sockaddr*)&sockAddr,sizeof(sockAddr)))
{
cout<<"connectfailed"<<endl;
return;
}
while(true)
{
charszBuf[MAX_PATH];
ZeroMemory(szBuf,sizeof(szBuf));
cout<<"YouSay:";
cin>>szBuf;
if(SOCKET_ERROR ==send(sockClient,szBuf,MAX_PATH,0))
{
cout<<"sendfailed"<<endl;
return;
}
intnRecvLen=recv(sockClient,szBuf,MAX_PATH,0);
if(nRecvLen>0)
{
//szBuf[nRecvLen]='
